引言内燃机车为我国牵引动力发展的主要方向。近年来有较大地发展,产品质量不断提高。随着成批生产,带来的劳动卫生学问题也就较为突出,尤其是机车制造和运行过程中发动机的强烈噪声振动,使工人及乘务人员的健康受到影响,据调查与之有关的工人和乘务人员中头痛、头晕、耳鸣、失眠、听力下降、易疲劳和一般的发病率都有显著地增高。这些事实足以引起我们对噪声控制技术的严重注意。在内燃机车制造部门中,受到噪声,振动作用较为强烈和反映较大的是柴油机试验站的工人。为了深入探讨其劳动条件和为今后进一步改善和新建更合理、更完备的试验站,我们 Introduction Diesel locomotives are the main direction for the development of traction power in our country. In recent years there has been a greater development, product quality continues to increase. With the mass production, the problems of labor hygiene are also prominent. In particular, the strong noise and vibration of engines during the manufacture and operation of locomotives have affected the health of workers and crew members. According to the investigation of the workers and Flight attendants in the headache, dizziness, tinnitus, insomnia, hearing loss, fatigue and general incidence rates were significantly higher. These facts are enough to arouse our serious attention to noise control technology. In the diesel locomotive manufacturing sector, workers exposed to noise and vibration are more intense and reflect more diesel test stations. In order to further explore its working conditions and to further improve and create a more rational and complete pilot station in the future, we
